Wikipedia: The Surra de Bunda is a dance invented by the group Tequileiras do Funk, from São José dos Campos, São Paulo, Brazil, which involves a female dancer “beating” her buttocks into a man’s face. It gained international attention by mid-2010. The phrase Surra de Bunda in Brazilian Portuguese loosely means “butt beat,” “butt pounding” or, more accurately, “punishment by ass.”
